摘要： PURPOSE:To provide a heat resisting vane which is constituted to have excellent erosion resistance, increase a high temperature strength, and reduce weight. CONSTITUTION:A core part 1 is formed of a heat resistant and light ceramics composite material (CMC) and a skin 2 is formed of W and an alloy thereof or Mo and an alloy thereof, having heat resistance and erosion resistance. This constitution prevents the occurrence of a damage owing to a combustion gas jet flow injected through the nozzle 11 of a rocket motor 10 and provides a light heat resisting vane 8 the high temperature strength of which is high.

摘要： PURPOSE:To provide an extension nozzle which can be employed to a rocket motor in which spin operation is not carried out and a large typed rocket motor, and in addition which can maintain the generation rate of abandonment fault at a low level. CONSTITUTION:The rear end of a supporting rail 10 is connected to the rear end side of a fix nozzle part 2 being allowed to rotatably and apartably around tangent line direction of the fix nozzle part 2. A rock pin 16 provided on the front end side of the supporting rail 10 is connected to a front side hook 17 provided on the front end side of the fix nozzle part 2 by fixing apartably. A torsion spring 20 for being placed the rear end of the supporting rail 10 apart from the fix nozzle part 2 by such way that separation force for separating the rock pin 16 from the front side hook 17 following with extension movement of a moving nozzle part 3 is applied on the rock pin 16 and rotating force around the tangent line direction of the fix nozzle part 2 is applied on the supporting rail 10 whose front end side is placed apart from the fix nozzle part 2, is provided between the supporting rail 10 and the fix nozzle part 2.

摘要： Method and apparatus are disclosed for automatically and remotely removing unwanted organic films from surfaces of vehicles and satellites in space. A particle beam generator (12) draws molecular oxygen from an on-board supply chamber (14) and develops a stream of positively charged oxygen ions (40). These ions are directed towards a surface or component of a spacecraft such as a solar cell, radiation emission aperture, or sensor objective lens (44) which has been coated by an opacifying, organic contaminant layer (42) that impairs the efficacy of the spacecraft. The ions (40) bombard the contaminant layer (42) and remove it by both kinetic interaction and chemical oxidation. Spacecraft surfaces and components may be restored and renewed to their original operational capabilities through this method of volatilizing debilitating occluding residues which have been hardened by solar radiation away from the spacecraft as harmless gases (50).
